Cheap price, questionable booster

Purchased a boost from G4 to G1 and had to switch boosters because the first one was not competent. The second one that came in won two games in a row then proceeded to play poorly the next three games. The price is cheap and the seller is quite nice, however, it seems the booster does not use high ranked players for his service. Be advised, be cautious if purchasing boost as you could lose more LP than you started with.
